📰 What Happened: In 2023, Seattle revised its tree ordinance, making it easier for builders to remove trees on private property. Since then, weekly tree removals jumped from just 6 trees to 58. While over 90% were small-diameter trees (and the city claims twice as many were replanted), advocates argue saplings can’t replace the ecological benefits of mature trees.

🔍 A Closer Look: The city’s goal of 30% tree canopy by 2037 is slipping out of reach. A recent study shows that even planting trees on every suitable public site in Seattle wouldn’t be enough to compensate for the fact that the city is “slowly losing ground.” The Department of Transportation faces steep hurdles, like concrete removal and utility conflicts, which also limit its capabilities.

🧠 Why It Matters: Seattle underscores a broader urban challenge—how to densify responsibly without compromising the environment. With heatwaves and stormwater runoff intensifying, mature trees are vital urban infrastructure. Smarter design through city incentives could offer a way to build housing without cutting down urban forests.
